For the first time, scientists have created embryos that are a mix of human and monkey cells. The embryos, described Thursday in the journal Cell, were created in part to try to find new ways to ...

Scientists injected human stem cells into macaque embryos into a study on human development. Some of the embryos continued to develop for 20 days, researchers said. But the experiment has sparked an ...

A synthetic embryo can now be constructed from very early pre-embryonic cells – without the need for an egg or sperm. These were initially created in mice. In April, Chinese researchers created ...

Scientists in China this week say they’ve accomplished a first in bioengineering: creating embryo-like structures from monkey stem cells. The structures were implanted in surrogate female monkeys and ...

Scientists based in China have created a monkey chimera with two sets of DNA, experimental work they say could ultimately benefit medical research and the conservation of endangered species. The ...

Embryos made from stem cells, rather than an egg and sperm, appear to generate a short-lived pregnancy-like response in monkeys. Embryos made from stem cells—instead of a sperm and egg—have been ...
